Question

d) If 22 is added to the one-third of the square of a natural number the sum will be 49.
Find the number.​

Answer 1

Answer:

9

Step-by-step explanation:

Let the number = n

According to the question

If 22 is added to the one-third of the square of a natural number the sum will be 49

then,

22 + [(1/3)(n^2)] = 49

=> [66+(n^2)]/3 = 49

=> [66+(n^2)] = 49×3

=> n^2= 147-66

=> n^2= 81

=>n= +9 or -9

We will consider the number be +9 as it is a natural number

Answer 2

Answer:

number is 9

Step-by-step explanation:

let the number be x

.: x²/3+22 = 49

x²/3 = 49-22

x²/3 = 27

x² = 27*3

x² = 81

x = √81

x = 9
